Product details

Overview

SF2002PT from Taiwan Semiconductor is a 20A, 100V super fast recovery dual rectifier in TO-247AD package with positive center-tap configuration, 35ns reverse recovery time, 1.100V forward voltage at 20A/25°C, and 2.5°C/W junction-to-case thermal resistance - used in DC-DC converters and snubber circuits.

For engineers reviewing the SF2002PT datasheet, SF2002PT pinout, SF2002PT application, or SF2002PT equivalent, key selection criteria include V_RRM = 100 V, I_F = 20 A, t_rr = 35 ns, R_θJC = 2.5 °C/W, and dual die center-tap topology for balanced high-frequency rectification.

Technical Context

The SF2002PT integrates two identical silicon rectifier dies in a single TO-247AD package with shared cathode and isolated anodes, forming a positive center-tap configuration ideal for full-wave rectification without external center-tapped transformers. Its superfast recovery (t_rr ≤ 35 ns) minimizes switching losses in high-frequency SMPS topologies.

Designed for operation up to 150°C junction temperature, it delivers low forward voltage (1.100 V @ 20 A, 25°C) and low thermal resistance (2.5 °C/W), enabling compact heatsink designs in space-constrained industrial and lighting power supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse voltage; defines safe blocking capability in 100 V-rated DC-DC stages.
I_F	20 A - Continuous average forward current per diode; supports high-power output rails without derating below 100°C case temp.
t_rr	35 ns - Reverse recovery time; enables efficient operation up to ~500 kHz switching frequency with minimal tail current loss.
V_F @ 20A, 25°C	1.100 V - Forward voltage drop per diode; determines conduction loss of 22 W total at 20 A (2 × 1.1 V).
R_θJC	2.5 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink with predictable thermal rise under full load.
I_FSM	180 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in industrial power systems.

Pinout & Package

Package: TO-247AD (TO-3P), 3-terminal molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, and polarity marked on device body.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (A1)	Input terminal for first rectifier die	Connected to AC input leg 1; must be routed with low-inductance layout for fast recovery integrity.
Anode 2 (A2)	Input terminal for second rectifier die	Connected to AC input leg 2; symmetrical routing required to balance conduction and thermal stress.
Cathode (K)	Common output node (center-tap)	Provides full-wave DC output reference; carries full 20 A sum current; requires heavy copper pour and thermal via array.

Key Features

Superfast recovery (t_rr ≤ 35 ns)	Reduces reverse recovery charge (Q_rr) to <15 nC, minimizing switching loss and diode-induced voltage spikes.
Glass passivated junction	Ensures long-term reliability under humidity and thermal cycling; meets JESD201 Class 2 whisker resistance.
Low R_θJC (2.5 °C/W)	Permits direct bolt-down heatsinking without thermal interface pads in many 20 A applications, simplifying mechanical design.

Equivalent & Alternatives

The following parts are listed as comparable options for similar superfast dual rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2002CT	V_RRM = 200 V, t_rr = 35 ns, V_F = 1.15 V @ 20 A, TO-247 package, single cathode	Higher blocking voltage; same recovery speed but slightly higher conduction loss	Preferred where system requires margin above 100 V reverse stress or legacy ST design reuse
IXYS MUR2020CT	V_RRM = 200 V, t_rr = 35 ns, V_F = 1.10 V @ 20 A, TO-247 package, center-tap	Same V_F and t_rr, but 200 V rating and different thermal profile (R_θJC = 3.0 °C/W)	Drop-in compatible in layout; requires minor thermal validation due to +0.5 °C/W R_θJC

Compared with SF2002PT, STTH2002CT offers higher V_RRM at minor V_F cost, while IXYS MUR2020CT matches V_F and t_rr but trades 100 V rating for 200 V headroom and slightly reduced thermal performance - both require review of layout thermal vias and snubber damping when substituting.

FAQ

What is the maximum junction temperature rating for SF2002PT?

The SF2002PT has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version I2103. This rating applies across the full operating range and enables reliable use in sealed enclosures or high-ambient environments when thermal design respects the 2.5°C/W R_θJC limit. Derating curves confirm 20 A operation is sustained up to 100°C case temperature.

Does SF2002PT have AEC-Q101 qualification?

The base SF2002PT variant is not AEC-Q101 qualified; however, the AEC-Q101 version is designated SF2002PTH per Taiwan Semiconductor's ordering information. The "H" suffix indicates full AEC-Q101 stress testing compliance, including temperature cycling, HTRB, and ESD. For automotive-grade deployment, SF2002PTH must be specified - SF2002PT lacks this qualification and is intended for industrial/commercial use only.

What is the reverse recovery time (t_rr) of SF2002PT and under what test conditions?

The SF2002PT reverse recovery time is 35 ns, measured under the condition: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value is typical and guaranteed maximum, confirmed across production lots. It reflects performance at 25°C junction temperature and is critical for minimizing switching loss in high-frequency converters.

How does the center-tap configuration of SF2002PT affect PCB layout?

The SF2002PT's positive center-tap configuration requires symmetric routing of Anode 1 and Anode 2 traces to maintain balanced current sharing and thermal distribution between dies. The common Cathode (K) pad must be large, thermally connected to a heatsink plane via ≥6 thermal vias, and kept short to minimize inductance that could degrade t_rr performance. Unequal trace lengths or asymmetric copper pours may cause current imbalance and localized overheating.

What is the forward voltage (V_F) of SF2002PT at rated current and temperature?

The SF2002PT forward voltage is 1.100 V per diode at I_F = 20 A and T_J = 25°C, as specified in the Electrical Specifications table. At elevated junction temperatures (e.g., 125°C), V_F decreases to approximately 0.95 V due to negative temperature coefficient of silicon PN junctions. This behavior reduces conduction loss under thermal stress but must be validated against system voltage regulation margins.
